so that the power pulley 29, driven by a belt from a suitable source of power, will be continuously operated while the conveyers will be operated or permitted to remain i le, under the control of the clutch 30.

Before passing to the conveyerathe single faced corrugated web 10 passesv over. a

table 36 with the applied or first facing up- 45 is provided at one end of the .sprocket permost, so that the crowns of the corrugated web will loe-exposed downwardly to contactiwith an agglutinant-applying roll 37 which is mounted in bearings 38 on the frame. `A pan or ieservoir 39 contains the agglutinant to bev applied to the web and thelower portion of roll 37 rotates in this agglutinant. A scraper or squeeze-roll 40 is provided to remove the excess agglutinant from the periphery of roller 374 soV -that agglutinant, in the desired amount, will .be applied to the crowns ofthe corrugations on the web. A roller 41 is mounted in bearing`s 42 which are secured to the table 36 to hold the web in contact with roller 37. Suitable web-guides 36 areprovided on table 36. Table 36 isl provided with pihtles :or studs 43 which are pivotally held in bearl I ings 44 on the frame, so that the table can be' tilted as indicated by dot-ted lines in Fig.

2 to raise theweb and roller 4l, and separate the web from applying-roll 37. The purpose -of this separation is to prevent the web from adhering to the quick-setting agglutinant on roll 37 4when the operation of the conveyers is discontinued. A guide-roller tablef36 to prevent the corrugated web from being caught on the end of the table 36.

The mechanism for driving the applyingroll 37, comprises a belt-pulley 46 on or secured .to rotate with the power-pulleyy 29 so thatitwill be constantly'driven, a crossed belt 47, a pulley 48, drivenl by said belt, a l wheel 49, rotating with pulley 48, a sprocket-chain and a sprocket-wheel 51 secured to the` shaft 53 of -roll 37. Roll 40 is also constantly driven bya pinion 52 on shaft 53 which meshes with a gear 54 on the shaft of roll 40.

The mechanism for tilting the table 36 to *raise the web away from roll 37,comprises a lever.

I shaft 57 which is journaled'in the `frame'and is provided with arms 58 whichare connected to thetable by adjustable links 59. Shaft 57, arms 58, links 59 and their cnnections are relatively disposed so they will be approximately in deadcenter relation to automatically lock the table in p'osition to guide the web' to roll 37.

56, which is secured to a cross-` To insure the separation of the web and tilting of the table 36 every time the machine is stopped, lever 56 is connected to the clutch-controlling lever 31 so that the clutch which controls the operation of the feeding mechanism for the web will be coniointly controlled with the table 36 so that when the clutch is disconnected from the powerwlieel, the table 36 will, at all times, be in position to hold the web away from the agglutinant-applying roll- 37 and when. the clutch is operative andthe web is moving through the machine, the table will be in position to causethc crowns of the corrugated webs to Contact with the agglutinant on roll 37. ,The connection between the clutch-lever3l and lever 56 comprises a. link 60 which is pivoted to lever 56 and to a bell-'crank lever 61 which is pivotcd to the frame and is also connected by means of a link 62 to the clutch-lever 31. lVhcn lever 56 is shifted (assuming theparis to be in positionvshown in full lines in Fig. 2) it will, through connection 60, 61, 62 and 3l uncouple the clutch 30 to disconnect the driving mechanism for the conveyors from the power-wheel 29and will simultaneously separate driving-connection between the agglutinant-applying roll and the power-pulley cause's said roll to-be rotated continuously, both when the eonveyers are operative and when they are inoperative, at which time the web is held away from said roll by table 36. As a result of this continuous operation, a quick-setting agglutinant will not harden on the roll.

The invention thus exemplifies an improved machine for making corrugated boardv in which provision .is made for separating the web. from the agglutinant-applying roll when the web-feed mechanism is idle and in which the web-feed is controlled conjointly with the driving-mechanism for the conveying-mechanism, so that, whenever the' conveying mechanism is operating, the web will. be held or guided so that agglutinant will be applied thereto and when the conveying mechanism is idle, the web will be held away from the roll to prevent adhesion of the roll and web.

The invention also exemplifies a machine for applying the second facing upon corrugated board, .in which the agglutinant applying roll is constantly operated both Leases? whenl the web is moving and to prevent the agglutinant from hardening upon the roll in connection with means for separating the web from the roll when the web is stationary.

r A rlhe invention/is not to be understood as.

restricted to ,the details set forth, since these may be modified within the scope ofv theA appended claims', without departing from the spiritand scope of the invention..

,Having thus described `the invention,` /what I claim as new and desire to secure by liettersl Patent, is:
